Interactive Brokers allows existing accounts to request their full account be 'linked' to a Friends Advisor, Non-Professional Advisor, a Professional Financial Advisor or a Fully Disclosed Introducing Broker. These linkages include all cash and positions and are available to accounts which are not currently Advisor or Broker clients. There are a number of checks which are performed which may prevent the linking of an account, such as, but not limited to, trading permission incompatibilities between the Advisor or Broker Master and the client account, commission schedule1 differences, etc.
Accounts which are configured with an unbundled commission schedule will not be allowed to link to an Advisor or Broker account, unless the commission schedule is changed to bundled. In the Advisor and Broker account structures, commission schedules cannot be defined for client accounts. If not properly configured at the master level, changing your commission schedule to bundled may result in higher commission charges.
IBKR will process accepted requests at approximately 3:00 p.m. every Friday.
